Reported execution: speak the colour, then refine it
WPP describes Speaking in Colour as a voice-controlled tool made for Sherwin-Williams Coil Coatings. A user says a word or phrase; the system analyses millions of images through a search algorithm and optical recognition, then produces a palette. The user can add language such as ‘more turquoise’ or ‘dappled sun’ to change the result.
The campaign’s AI role is specific and legible. It does not pretend a machine has discovered a universal emotional meaning for colour; it turns a subjective verbal prompt into an editable starting point.
Our reading: ambiguity is the product brief
Colour selection often starts with language that is evocative rather than technical. The useful interface move is to accept that ambiguity and return something people can react to. A palette is not the answer; it is a conversation object between an imagined place, a user and a material decision.
That only works if revision remains easy. A system that treats its first interpretation as authoritative turns a creative aid into a confusing gatekeeper. Keep the prompt visible, offer adjustments and preserve a human colour review for production use.
Evidence boundary: personalised output is not universal perception
WPP establishes the intended mechanism and gives examples of the interactions. The page does not establish that the generated palette accurately represents every user’s description or that it improves a specified business outcome.
The transferable lesson is practical: use AI to make a fuzzy prompt manipulable, then make clear that the user, not the model, owns the final colour decision. Accessibility testing must remain part of that decision. Teams should also test whether the interface recognizes different accents, speech patterns and descriptive traditions before presenting it as universally personal.
